FIG. 4 is a flow chart of a method for cloud medical image analysis shown according to an embodiment of the invention.

Referring to all of FIG. 1 to FIG. 4, the method for cloud medical image analysis of FIG. 4 can be applied in the system 100 for cloud medical image analysis in FIG. 1. In step S401, the image input module 24 a of the electronic device 100 can obtain a medical image. In the present exemplary embodiment, the medical image is an ultrasound image. However, in other exemplary embodiments, the medical image can also be other types of image based on actual application requirement.

Next, in step S403, the electronic device 100 can quantify the medical image via the feature value acquisition module 24 b to obtain a feature value (also referred to as a first feature value).

For instance, after the electronic device 100 obtains the medical image, the feature value acquisition module 24 b can, for instance, perform a pre-processing (such as organization clustering or pixel clustering) on the medical image and quantify the features of the medical image after the pre-processing. In particular, the features of the medical image are, for instance, texture, intensity, or shape. However, the invention does not intend to limit the form of the pre-processing and the features in the medical image.

In an embodiment, the deep-learning model adopts a multi-resolution convolutional neural network. In general, the deep-learning model includes a plurality of layers, such as a plurality of convolution layers, a plurality of pooling layers, and a plurality of fully-connected layers. During the operation of the plurality of layers, a device having better computing ability is often needed for execution to effectively reduce process time. Therefore, when the computing ability of the cloud medical analysis platform 120 is better than the computing ability of the electronic device 100, the function of the CADe module 36 a or the CADx module 36 b can be executed by the cloud medical analysis platform 120 using the deep-learning model. Moreover, since the electronic device 100 only sends the feature value to the cloud medical analysis platform 120 for analysis, the electronic device 100 does not need to send a complete medical image to the cloud medical analysis platform 120. As a result, the transmission amount of data can be effectively reduced, and the performance of the system can be increased.

In particular, in an exemplary embodiment, a portion of the layer in the deep-learning model of the analysis module 36 can also be first executed by the electronic device 100. For instance, in step S403, the feature value acquisition module 24 b of the electronic device 100 can input the medical image to a portion of the layer in the deep-learning model to obtain the first feature value. After the cloud medical analysis platform 120 obtains the first feature value, the first feature value can be inputted to another portion of the layer in the deep-learning model in step S407 to obtain the analysis result. Via this method, the operational efficiency of the deep-learning module can be increased, and the operation of the system 1000 for cloud medical image analysis can be more flexible.

It should be mentioned that, in the invention, the implementation of the CADe module 36 a and the CADx module 36 b in the analysis module 36 is not limited, and in another embodiment, the CADe module 36 a and the CADx module 36 b can also be respectively implemented using a machine-learning algorithm (such as logic regression or support vector machine) based on actual application requirement and be trained via a plurality of training images.

After the feature value is obtained, the electronic device 100 can send the feature value to the cloud medical analysis platform 120 via a wired or wireless method. The cloud medical analysis platform 120 inputs the received feature value to the CADe module 36 a in the analysis module 36 to generate an analysis result. In particular, the CADe module 36 a is used to determine the location of the tumor in the medical image according to the feature value and generate a corresponding analysis result. In other words, the analysis result generated by the CADe module 36 a is used to represent the location of the tumor in the medical image.

Next, the cloud medical analysis platform 120 can send the analysis result to the electronic device 100. The electronic device 100 can display via the human-machine display interface (such as a touch display screen (not shown)) thereof such that the user (such as a doctor) can learn the location of the tumor in the medical image.

However, it should be mentioned that, the electronic device 100 can also send a feedback message to the cloud medical analysis platform 120 according to the analysis result. The cloud medical analysis platform 120 uses the feedback message and the first feature value of the medical image to make the CADe module 36 a self-learn.

For instance, the electronic device 100 can learn the location of the tumor via the analysis result returned by the first embodiment, and the electronic device 100 can cut the medical image in the first embodiment according to the location of the tumor to capture the medical image of the tumor region as the medical image of the second embodiment.

After the medical image of the second embodiment is obtained, the electronic device 100 can obtain the feature value according to the medical image via the method of generating the first feature value and send the feature value to the cloud medical analysis platform 120. The cloud medical analysis platform 120 inputs the received feature value to the CADx module 36 b in the analysis module 36 to generate an analysis result. In particular, the CADx module 36 b is used to determine whether the tumor in the medical image is benign or malignant according to the feature value and generate a corresponding analysis result. In other words, the analysis result generated by the CADx module 36 b is used to represent whether the tumor in the medical image of the second embodiment is benign or malignant.

Next, the cloud medical analysis platform 120 can send the analysis result to the electronic device 100. The electronic device 100 can display via the human-machine display interface (such as a touch display screen (not shown)) thereof such that the user (such as a doctor) can learn whether the tumor in the medical image is benign or malignant.

However, it should be mentioned that, the electronic device 100 can also send a feedback message to the cloud medical analysis platform 120 according to the analysis result. The cloud medical analysis platform 120 uses the feedback message and the first feature value of the medical image to make the CADx module 36 b self-learn. For instance, in the analysis result, a malignant tumor may be misjudged as benign or a benign tumor may be misjudged as malignant. The user (such as a doctor) of the electronic device 100 can add the correct determination result in the feedback message, and the cloud medical analysis platform 120 can make the CADx module 36 b self-learn according to the feedback message.

In other words, in the second embodiment, the electronic device 100 can obtain a feature value.

After the feature value is obtained, the electronic device 100 can send the feature value to the cloud medical analysis platform 120. The cloud medical analysis platform 120 inputs the received feature value to the CADe module 36 a in the analysis module 36 to determine the location of the tumor in the medical image.

For instance, when the CADe module 36 a performs an operation using a region-wise algorithm, the CADe module 36 a can determine the location of the tumor in the medical image corresponding to the feature value using the feature value obtained from the electronic device 100. When the CADe module 36 a performs an operation using a pixel-wise algorithm, the CADe module 36 a can determine whether the various pixels in the medical image corresponding to the feature value are a tumor using the feature value obtained from the electronic device 100 and determine the location of the region formed by the pixels of a possible tumor as the location of the tumor.

When the location of the tumor in the medical image is determined, a tumor may be present in the medical image. At this point, the CADe module 36 a can generate a second feature value according to the received feature value. In particular, the second feature value is, for instance, the same as the feature value received by the CADe module 36 a from the electronic device 100 or a feature value generated from another process, and is not limited thereto.

Next, the CADe module 36 a sends the second feature value to the CADx module 36 b. The CADx module 36 b generates an analysis result according to the second feature value. In particular, the CADx module 36 b is used to determine whether the tumor in the medical image is benign or malignant according to the second feature value and generate a corresponding analysis result. In other words, the analysis result generated by the CADx module 36 b is used to represent whether the tumor in the medical image is benign or malignant.

Next, the cloud medical analysis platform 120 can send the analysis result to the electronic device 100. The electronic device 100 can display via the human-machine display interface (such as a touch display screen (not shown)) thereof such that the user (such as a doctor) can learn whether the tumor in the medical image is benign or malignant.

Similarly, the electronic device 100 can also send the feedback message to the cloud medical analysis platform 120 according to the analysis result such that the cloud medical analysis platform 120 makes the CADx module 36 b self-learn according to the feedback message and the second feature value of the medical image.

In other words, in the third embodiment, the electronic device 100 can obtain a feature value. The cloud medical analysis platform 120 respectively executes the CADe module 36 a and the CADx module 36 b according to the feature value sent by the electronic device 100 and generates an analysis result. The user (such as a doctor) of the electronic device 100 can learn whether the tumor in the medical image is benign or malignant according to the analysis result and can provide the feedback message to the cloud medical analysis platform 120 to make the CADx module 36 b self-learn.

Via this method, the electronic device does not need to actually execute the CADe module and/or the CADx module, and therefore the computational load of the electronic device can be effectively reduced. Moreover, since the electronic device only needs to send the feature value to the cloud medical analysis platform for analysis, the electronic device does not need to send a complete medical image to the cloud medical analysis platform. As a result, the transmission amount of data can be effectively reduced, and the response time of the system can be reduced.
